WebFeb 11, 2024 · The way n is documented in slice functions right now, this behavior in slice_sample looks like a bug. If n is greater than the number of rows in the group (or prop > 1), the result will be silently truncated to the group size. Maybe clarifying this behavior for slice_sample could minimize the confusion? WebNormally t-test is supposed to be used for comparing data of small samples, e.g. <30.

Larger values introduce noise in the labels and make the classification task harder. WebJul 28, 2024 · As the sample size increases, n goes from 10 to 30 to 50, the standard deviations of the respective sampling distributions decrease because the sample size is in the denominator of the standard deviations of the sampling distributions.
